支付寶開放平臺官網(wǎng)

用自己手機支付寶掃碼登錄 根據(jù)頁面提示填寫自己真實信息 進去之后

東西主要用的就在這里

sdk 在 點文檔 找到 下面的開發(fā)工具

創(chuàng)建demo實例分析

弄新版的 里面有對應java代碼 復制來 修改處都換成自己的

里面需要更換的地方 都有提示

下面是第一次用的是時候（總結(jié)來說就是 使用工具 生成密鑰 復制生成的公鑰填到RSA2公鑰中 生個應用公鑰 支付寶公鑰（將來要用的就是 工具生成的私鑰 支付寶公鑰））

弄過的話想換 就是更換應用公鑰 會自動生成 保存即可

下載好工具后打開

還需要證書 按下面網(wǎng)址往下滑找到公鑰證書方式教程
公鑰證書方式


全選了 這里好像沒驗證過 應該沒關系放棄了

上面失敗了 從來



這次上傳好了






放棄上面了
插件地址

重啟IDEA

下面弄錯了選擇第二個 QuickStart

提供下面3處內(nèi)容

運行時說沒有授權碼 下面嘗試弄授權碼
下面失敗

下面先去注冊個小程序 沒什么用里面沒得授權碼啥的
